Image Viewing
Problem Cause Measure
Part of the field of view is
missing.
The field of view is
invisible.
The brightness of the field
of view is not uniform.
Images are dark.
Devices are not attached correctly. Attach the devices correctly.
The optical path switching lever of the tube is
positioned partway.
Position the lever correctly.
The nosepiece is not turned to the click
position or is placed in the vertical view state.
Firmly turn the nosepiece to the click position for
stereoscopic view to bring the objective into the
optical path.
The objective and/or sample is contaminated
with dirt or dust.
Clean as needed.
The light intensity of illumination is too low. Adjust the light intensity to an appropriate level.
The turret of the epi-fluorescence attachment
is not at the correct position. Set the turret at the correct position by turning the
filter cube switching knob.
Dirty or dusty field of view
The objective is contaminated with dirt or dust. Clean as needed.
The sample is contaminated with dirt or dust. Clean as needed.
One side of the image is
blurred or images are

Operation
Problem Cause Measure
Even when looking with
both eyes, an image does
not appear as a single
image. The interpupillary distance has not been
adjusted.
Adjust the interpupillary distance.
The diopter has not been adjusted. Adjust the diopter distance.
Eyes become fatigued.
The interpupillary distance has not been
adjusted.
Adjust the interpupillary distance.
The diopter has not been adjusted. Adjust the diopter distance.
Brightness is inadequate. Adjust the brightness of the illumination.
Changing magnification
results in large focal deviation.
The diopter has not been adjusted. Adjust the diopter distance.
The focal deviation is large
when objectives are switched.
The diopter has not been adjusted. Adjust the diopter distance.
The torque of the focus
knob is heavy.
The torque of the focus knob is too tight.
On devices with a torque adjustment ring, loosen the
torque adjustment ring to some extent. On devices
with a focus knob on both sides, turn the focus knobs
in the direction for loosening the torque.
The focus becomes less
sharp over time. The
vertical position of the
zooming body may slide
due to various loads (such
as its own weight or the
load of the counterbalance
spring inside the focus
unit).
The torque of the focus knob is too loose.
On devices with a torque adjustment ring, tighten
the torque adjustment ring to adjust the torque to
an appropriate level. On devices with a focus knob
on both sides, turn the focus knobs in the direction
for tightening the torque.
